Last updated: August 2026 dataSodium nitrite—the commercially dominant product in this heading—is a critical intermediate in dye manufacturing, a curing agent in meat processing, and a corrosion inhibitor in industrial fluids. The US schedule separates sodium nitrites (2834101000) from other nitrites (2834105000), and India leads US imports under this heading, with China also a significant source. Nitrites destined for food-contact or meat-curing applications are subject to FDA and USDA FSIS oversight depending on end use, adding a regulatory layer beyond standard customs clearance.

The HTS classification is the same regardless of end use—both food-grade and industrial-grade sodium nitrite enter under 2834101000. However, food-grade material is subject to FDA admissibility review, and sodium nitrite used in meat-curing preparations may also fall under USDA FSIS jurisdiction. Importers should maintain grade-specific certificates of analysis and consult a licensed customs broker or the relevant agency for admissibility guidance.
Sodium nitrite (NaNO₂) is classified under heading 2834 as a nitrite, while sodium nitrate (NaNO₃) falls under heading 2834 as a nitrate. The chemical distinction—oxidation state of nitrogen—is the controlling factor; suppliers' certificates of analysis confirming the molecular formula are essential to avoid misclassification.
